Hi
Like others (probably) I've left my car in the garage for the past 6 weeks and today I thought I ought to give it a run. Unfortunately the battery is flat and I can't get into the car. Any ideas what I should do?

Mine flat too after a week or so. In for a service and they said battery no good under load. £75 for a new battery.
Car is may 2017
I have been starting it with a little starter thing I bought. About the size of an iPhone.
I can’t see the point of changing the battery as the same will happen.
I wonder how long they should last without use?
